BMW limits its warranty coverage in the US (and probably the ROW) to exclude damage caused by abuse. If someone in the US buys a manual transmission car and does max rpm clutch drops until something breaks, or does a money shift and blows the motor, do think BMW will fix the car because it is afraid of lawyers?

It's very simple; in the US you can't include a feature on something and then void their warranty because they used it too many times.
